Invited Talk 1: Junji Shikata (Yokohama National University, Japan) |
| Title: “Advanced Cryptography Based on PQC for Future Communication Services” | |
| Date : August 22, 11:50 |
Abstract:
By Advanced Cryptography, we mean cryptographic schemes that claim superiority over conventional cryptographic primitives in terms of added or improved functionality, or new functionality, such as being able to solve problems that were difficult to solve with the conventional ones. For example, advanced cryptography includes ID-based encryption, attribute-based encryption, broadcast encryption, homomorphic encryption; and ID-based signature, aggregate signature, attribute-based signature, ring signature. This talk explains advanced cryptography based on PQC for their utilization under future emerging environments such as 5G beyond (B5G). In addition, Japanese research projects on advanced cryptography based on PQC for secure wireless communication and their activities are introduced and explained.
Biography:
Junji Shikata received the B.S. and M.S. degrees in mathematics from Kyoto University, Japan, in 1994 and 1997, respectively, and the Ph.D. degree in mathematics from Osaka University, Japan, in 2000. From 2000 to 2002, he was a Postdoctoral Fellow with the Institute of Industrial Science, The University of Tokyo, Japan.
